The chromosomes, which come to lie on the floor of the chamber, are observed using a phase-contrast microscope whose optical train is inverted, i.e., with condenser above the object, and objective lens below.doi:10.1007/978-1-4613-4470-4_5Callan, Harold G...

The limits of conventional light microscopy (“Abbe-Limit“) depend critically on the numerical aperture (NA) of the objective lens. Imaging at large working distances or a large field-of-view typically requires low NA objectives, thereby reducing the op

Fine-structure ceramic under the scanning electron microscope The homogeneous distribution of the two glass phases is shown by the comparison of the SEM photos. Photos 1 and 2 show the etched surface of VITADUR ALPHA and VITA VM 7 with identical coefficients of thermal expansion (CTE). The ...
of BAPTA or BAPTA-like compounds. Because of their similarity to fluoresceins and rhodamines, such new compounds would be optically compatible with almost any fluorometer or fluorescence microscope or flow cytometer now in use for immunofluorescent detection. Because of the ready availability of such ...
In our work, we present a new strategy focused on the improvement of the catalytic performance of iron catalysts for FT synthesis, which is based on mobile and versatile promoters, such as bismuth. In contrast to the conventional promoters, which are usually considered immobile and localized over...
The match between the experimental measurement and the theoretical calculation confirms that the NA of the objective is 0.50, as designed (Methods). This result also indicates that the r.m.s. wavefront error is low. Like all other infinity-corrected microscope objectives, underfilling the ...
77Citations 17Altmetric Metrics Abstract Direct identification of the active sites of a working catalyst is still a major problem in heterogeneous catalysis. Here we present an operando scanning tunnelling microscopy study, in which insight into the nature of the active sites was obtained for the co...
